Subject: [PATCH] fix(avlivewire): encoder prefix + reader hoist

HandsPayload.encoded() wrote min(count,255) in the header but looped
over all hands; use hands.prefix(255) so header and body agree.

Hoist the float reader func f() to the outer hand loop, matching
FacePayload style; declared once per hand instead of per point.
